[FIXED] Download of an email attatchment on Jenkins

Issue

I have been testing the Jenkins "Poll Mail Trigger" plugin to trigger a project via email. To develop the project I need to download the attached file that is sent.

In the project settings, I enable the only download option that exists: "Download to a timestamped Directory".

Also, the only information regarding the download is this: "The Attachments field, allows you to determine what to do with email attachments. If attachments are downloaded, the pmt_attachmentsDirectory variable with be set to the download directory."

Then, after doing several tests without configuring any directory for the download of the attached file -assuming that the download should have been automatic-, I proceeded to change the environment variables in the Jenkins configuration, I put the following:

• Name: pmt_attachmentsDirectory
• Value: *D: *

So, what I'm trying to do is save the file to my Drive D: \

The file is never downloaded to the specified disk, and just for verification, I am trying to move the file with the following Windows command:

move "% pmt_attachmentsDirectory%" "D: \ Users \ wrodriguez \ Downloads \ Test_Programs"

And finally it throws me the following output: "The system cannot find the specified file."

So, I am really lost here, can anybody help me with this issue? Is there another plugin on Jenkins that I can use to download an attatchment?

Thanks for your help.

Solution

I haven't worked on that plugin (or Jenkins) in 5 years, so forgive my rustiness.

Looking at the code, the plugin creates a timestamped folder, and saves any attachments there.

It then injects an environment variable named pmt_attachmentsDirectory into the Jenkins job instance's environment variables - the value is the absolute path of folder (it's not configurable).

Troubleshooting:

• have you enabled saving Attachments in the Plugin options?
• check the job instance's environment variables - does it have pmt_attachmentsDirectory listed?
  • print the value of pmt_attachmentsDirectory - e.g. echo "%pmt_attachmentsDirectory%" - what does it say?
  • does the directory exist?
  • does the directory contain any files?
• does the "View Polling Log" have any errors?
• do the Jenkins logs have any errors?

Other notes:

• "% pmt_attachmentsDirectory%" - shouldn't have a space e.g. should be "%pmt_attachmentsDirectory%"
